STEAM-VALVE FOR RADIATO RS.

SPECIFICATION forming part of Letters Patent No. 231,039, dated August10, 1880.

Application filed February 9, 1880.

To all whom it may concern:

Be it known that I, EDWARD Hints, of Rochester, in the county of Monroeand State of New York, have invented a new and useful Improvement inSteam-Valves for Radiators, which improvement is fully set forth in thefollowing specification and accompanying drawing.

The object of my invention is to produce a valve for steam-radiators bymeans of which steam may be admitted into the radiator through oneopening in the side of the valvechamber, and the water from thecondensed steam returned through a pipe leading from the bottom at adistant part of the radiator into the valve-chamber through anotheropening in the side of the same, thus securing a free circulation of thesteam within the radiator and dispensing with one valve and extra pipe,commonly used.

The drawing represents a side elevation of a part of a steam-radiatorwith my improved valve and pipe connection attached, the same beingpartially sectioned.

Referring to the drawing, A represents a radiator, of any suitable makeor form, resting upon afioor, B. O is a steam and water valve, beingplaced partly above and partly below the floor, as shown.

Near the upper end of the valve-chamber is an opening, a, whichcommunicates with the base of the radiator through a connectingnipple,b. Near the bottom of the chamber containing the valve is anotheropening, a, beneath the floor and in line with the other opening, a.

D is a pipe beneath the floor under the radiator, having one end turnedupward through the floor and entering an orifice, d, in the bottom plateof the base of the radiator, the other end of which pipe descends andenters the opening 0 of the valve-chamber, as shown. This pipe D isdesigned to convey away the water resulting from the condensation ofsteam within the radiator, which water is discharged into thevalve-chamber above the valve-opening 6, and descends to the boilerthrough the pipe connecting said boiler with the valve, up through whichpipe steam also flows to the radiator.

The valve-openin g e is merely a conical open ing through a diaphragm,and the valve f a conical plug fitting said opening at the end of astem, g, reaching down through a stuffing-box, k.

The stem 9 is rotated by means of an ordinary hand wheel, h, and isprovided with a screw-thread, so as to move-up or down as the handwheelis turned one way or the other, these parts being those in common use insimilar valves.

Heretofore some radiators have been put up with a valve at each end ofthe radiator, with an independent line of pipe connecting the boilerwith each valve, one line of pipe and valve to convey steam to theradiator and the other to convey water back to the boiler. Others havebeen put up with a single valve and line of pipe, in which the steam isallowed to tlow from the valve to the radiator and the water from theradiator to the valve, through the same opening in the side of thevalve-chamber. The former manner of putting up radiators isobjectionable, as it requires two valves and two separate lines of pipeconnecting the radiator and boiler, which, if the former be separatedsome distance from the latter, adds materially to the cost; and thelatter, although requiring but one valve and one line of pipe, isobjectionable, as the inflow of steam to the radiator tends to crowd thewater back and heap it up in distant parts of the same, which waterseals the passages and prevents a free circulation of the steam throughthe radiator, on account of which large patches of the surface of theradiator remain cold and radiate little or no heat.

By making an opening at d, opposite to the infiow a, the water drivenback by the advancing steam finds easy escape and does not accumulatewithin the radiator to obstruct the circulation of the steam or renderany part of the radiator useless; and by connecting said 1 opening (I,by means of a pipe, D, with the chamber of the valve O, as shown, thevalve and whole line of pipe commonly used to connect the opening atwith the boiler is dispensed with.

The opening eis made larger than the opening a, to admit of an easy flowof the water downward through the former while the steam ascends to theradiator.

It is not essential that the pipe D be placed below the floor, as shown,but the whole may be raised a few inches above the floor, in which casethe dotted line B may represent the floor upon which the whole apparatusstands.

I do not claim, broadly, a chamber over a steam-valve having an outletand an inlet openin g through the wall of the chamber over the valve,such construction being old.

V hat I claim as my invention, and wish to secure by Letters Patent, is-

In combination with a radiator, A, a valve, 0, provided with openings aand c, substantially as described, and a pipe,*D, connecting an opening,d, in the radiator with the lower opening, 0, of the valve,substantially as described and shown.
